  • Closeup cross-section of a large tree with many rings. Caption: This is a cross-section of a redwood tree.

    David Stahle travels to ancient forests around the world, collecting tree rings to learn more about major climate and historical events dating back hundreds and thousands of years. With help from the National Science Foundation, he uses dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle runs the Tree-ring Lab at the University of Arkansas, where he and fellow tree-ring researchers are learning that a trend of global warming began in the 1800s and continues today, brought about by changes in tropical sea surface temperatures of no more than a few tenths of a degree Celsius. Today Stahle is working with hydrologists and government planners in California and throughout Mexico to plan for drought and climate change events.

  • Illustration of trees growing on a mountain. Caption: Some of these forests grow on mountains.

    Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko and Mei-Lei are resting in the shade of a tall tree. Mei-Lei is wondering whether Moko will be leaving her and saddened by this thought she walks away. Moko sets off to try to find her in the tropical forest. Droplets of water stream down from the trees like rain. Night falls and Moko can no longer see anything. He decides to wait until morning to go on. The next morning, Mei-Lei has returned and she is smiling because she sees that she must mean a lot to Moko since he came all this way to find her. He thinks that the trees have stopped crying now that Mei-Lei is no longer sad.

  • Illustration of a tree with a few leaves on the branches. Caption: This bark can be very thin, or quite thick.

    Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, after a long voyage Moko arrives in Amazonia. He thinks that all of the people from this country must be giants because the trees in the forest he comes across are enormous. He climbs the tallest tree he can find and looks out towards the landscape and sees that the trees stretch out as far as the eye can see. Moko wonders if this is what the end of the world looks like. He feels quite alone and makes a wish to the stars to put a new friend on his path.

  • An aerial view of a canopy of trees.

    Can trees really combat climate change? For eons, nature has relied on photosynthesis as a means to keep carbon dioxide levels from getting out of control. This episode discusses ways trees can help solve climate change. Part of the “It’s Okay to Be Smart” series.

  • A spherical organism only partly in focus. Long leg-like protrusions with bulges at the end. Caption: These colonial rotifers secrete a jellylike substance

    The diversity of rotifers is stunning, and many different species are overviewed. Planktonic rotifers have special adaptations for open water life. Nematodes (roundworms) include a number of important human parasites, seldom seen but easily found. Tree moss, leaf litter, and compost piles swarm with nematodes.

  • Sunlight is shining through in a forest with large number of trees.

    There is an elaborate social network living in forests. It’s called the “Wood Wide Web,” a massive and intricate network of fungi that exchange water, nutrients, and chemical signals with plants. This network of fungi is essential to the health and function of forests and to controlling climate change. Part of the "It's Okay to Be Smart" series.

  • Graphic of four islands close to each other. Each island has lizards on it. Caption: evolved independently on each island.

    Working in the islands of the Caribbean, biologist Jonathan Losos has discovered the traits that enable dozens of anole species to adapt to different vertical niches in the forest. Differences in limb length, body shape, and toepad size allow different species to flourish on the ground. However, lizards living on thin branches or high in the canopy have different characteristics. These varied adaptations have played a key role in reproductive isolation and the formation of new species.
